Definitions
- the invention relates to a roller blind for a roll-up cover especially for covering machines, windows, garage doors etc., with a helically wound torsion spring located in a tube as an energy store, the first end of the spring rotatably connected to the tube and their second spring end connected in a rotationally fixed manner to a first of two axle journals which form an axis about which the pipe is rotatable, wherein one end of the cover is attached to the outer periphery of the tube.
- Roller blinds of this type have been known for a long time.
- the invention has therefore set itself the task of one Roller blind of the type described above to ensure that the operation the roller blind's inevitable changes in length of the torsion spring with simpler Funds are balanced.
- the object is achieved in that on the first axle journal a holding piece pointing into the interior of the tube Attachment of the second spring end and also in the tube a non-rotatable therein however, axially freely movable slider for fastening the first Spring end are provided.
- the spring ends can be easily locked when the holding piece and / or the slider on their respective circumference with a thread-like Groove are provided, their dimensions for receiving and fixing the spring ends serve in such a way that they unite in the groove Form a press fit when the torsion spring is relaxed.
- the slider which suitably the inner cross section of the tube is matched with the inner surface of the tube form. Correspondingly smooth surfaces of the fit parts then ensure for the lowest possible friction during blind operation.
- the invention ensures that the torsion spring can react unhindered in their axial direction to changes in length, at the same time, however, the individual parts used were manufactured using simple means and can be assembled without sacrificing long life the roller blind would have to be cut back.
- FIG.1 shows a longitudinal section by a roller blind according to the invention, the associated, up and developable cover has been omitted.
- a length about the width of a cover to be wound corresponding pipe 1 is at its two pipe ends 1a, b, respectively provided with a hub 2, which are rigidly attached to the tube 1, for example in that they have been pressed into the associated pipe ends 1a, b are, as is indicated in the drawing.
- a slight clearance between the hub 2 and the Axle journal 4a, b ensures their low-friction mutual rotatability.
- the hub 2 can also be provided as a roller bearing, wherein then instead of the clearance fit a press fit between the hub 2 and the journal 4a, b is required.
- this is the tube 1 to Axle pins 4a, b - which form an axis 6 - around this axis 6 with low friction rotatable.
- a holding piece 7 directed into the interior of the tube 1 On a first journal 4a in the pipe end 1a is also a holding piece 7 directed into the interior of the tube 1 is provided its cylindrical periphery has a spiral groove 7a, the dimensions that of a helically wound, located in the tube 1 Torsion spring 8 are adjusted so that their (second) spring end 8b the holding piece 7 can be screwed on. It is ensured that the spring end 8b forms a press fit with the groove 7a when the torsion spring 8 is relaxed, namely when the cover on the tube 1 is wound up.
- a slide 9 is axially freely movable in the pipe 1 provided, the cylindrical lateral surface 9a for this purpose with the inner surface 1c of the tube 1 a smooth play fit formed.
- the slider 9 is also against rotation in the tube 1 by means a key 10 provided on it secured into a axially parallel slot 1d of the tube 1 engages, the length of which in the direction the axis 6 is chosen so that the slider 9 all changes in length is able to follow the torsion spring 8 during the blind operation.
- a coaxial pin 9b corresponding to the holding piece 7 Slider 9 is provided with a groove 9c, the dimensions of which in turn those the torsion spring 8 are adjusted so that their (first) spring end 8a can be screwed onto the pin 9b and with its groove 9c also already forms a press fit when the torsion spring 8 relaxes is.
